From 5bf6c07a1843813d0065feaaecba622d49148d7e Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Thu, 30 Apr 2015 15:12:42 -0400 Subject: tile: add and enable support functions This change enables the generic strncpy_from_user() and strnlen_user() using word-at-a-time.h. The tile implementation is trivial since both tilepro and tilegx have SIMD operations that do byte-wise comparisons against immediate zero for each byte, and return an 0x01 byte in each position where there is a 0x00 byte.
